In a practical embodiment the invention comprises a wagon-like vehiclehaving'front wheels at and b on an axle 0, provided with a suitabletongue (1, rear wheels e and f on an axle g, and two side sills h and"L, mounted on the axles and suitably braced and floored to form a mainframe or body part of the vehicle. Two posts B and B, forming base partsof a derrick, are securely fixed upon the forward end of the main frameand provided with a pivotal rod at their upper ends, and two side pieces0 and C, comprising parts of a ladder-like folding part of the derrick,are supported pivotally somewhat near their lower ends on the rod andprovided with braces k and 7c, that are bolted to their up per parts andalso to the side sills of the main To all whom it ntcty concern: brokenw y,

Be it known that we, WILLIAM D. VAN AnsnALE and DAVID It. SPEARMAN,citizens of the United States, residing at Pendleton, in the county ofMadison and State of Indiana, have invented new and useful Improvementsin Machines for Reviving Gas-Wells; and we do declare the following tobe a full, description of the invention, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to means for reviving natural-gas wells that havebecome more or less exhausted and lack the pressure necessary to forcethe water and sandy matter out of the tubing thereof, resulting in thestoppage of the flow of gas, the invention having particular referenceto portable machines i and apparatus whereby the water may be clear, andexact drawn from the wells and whereby also the tubing may be swabbedand cleared of the coating of gummy substance which ordinarily isdeposited therein by the flowing gas.

It is well known that many gas-wells have become useless on account ofobstructions therein after the gas-pressure becomes low, although theremay yet be considerable volumes of gas in the wells or in the sources ofsupply; and the object of the present invention is to provide convenientand portable means for reviving such wells at small cost and be adaptedto cheaply reclean the wells at more or less frequent intervals, asoccasion may require.

With the above-mentioned and minor obl 'ects in view the inventionconsists in a vehicle provided with a folding derrick, a wind ing drumand cable, an engine to operate the drum, a pump-bucket, and a swab; andthe invention consists, further, in the parts and combinations andarrangements of parts, as hereinafter particularly described, and reiferred to in the claims.

Referring to the drawings, Figure 1 is a side elevation of the machineand apparatus; Fig. 2, a front elevation thereof Fig. 3, a top planthereof; Fig. 4, a fragmentary sectional 1 view of the winding-drumgearing on the in clined plane of the line A A in Fig. 1; Fig. 5, afragmentary transverse vertical sectional view of the main frame anddrum-gearing at l the drumaxis; Fig. 6, a side view, partly side piecesC and (1 An axle m, on which two pulleys D and D are mounted, issupported by the upper portions of the side pieces 0 and C but thepulleys may be otherwise hung to the top of the derrick, if preferred.Then the side pieces C and C are upright, their lower ends rest on theside sills h andi to partially relieve the rod j of strains.

A shaft n is mounted rotatively on the side sills h and i near the footof the derrick and have two pulleys E and F secured thereto near theends thereof. An explosive-engine G, having a drive-pulley p, is mountedon the rear part of the main frame or body of the vehicle, and a belt qconnects the pulley p with the pulley F for driving the shaft a. A shaft1" is supported in a pair of bearings H and H, that are supportedmovably on the side sills h and i, a pulley I is mounted on the shaft 1opposite to the pulley E, and a pulley J is mounted also on the shaft 1"opposite to the pulley F. A winding-drum K is mounted on the shaft 1 andis attached to the pulley I, and a winding-drum K is mounted also on theshaft 1" and is attached to the pulley J A cable 3 is connected toframe, there being rounds Z attached to the the drum K and extends overthe pulley D, and a cable tis connected to the drum K and extends overthe pulley D.

A pump-bucket is attached to the cable 5- and comprises a hollow vesselL, composed of a long piece of pipe having a loop u on its upper end forconnecting it to the cable, the upper end of the vessel being open andthe lower end of the vessel being partially closed andv provided with avalve-seat o therein and a central opening w. A valve M is arranged soas to operate on the seat and has a dartshaped head N, with a shoulderas and connected to the valve by a stem y, extending through the openingw, the shoulder being adapted to engage the closure of the end of thevessel when the valve opens. The bucket is to operate in connection withthe well-tubing.

A swab is attached to the cable t and comprises a rope 0, having twoswab-packings P and P attached thereto, between which brushes 11 and 12are formed on the rope, preferably of pieces of rope twine. A sinker Qis attached to the lower end of the rope O and forms part of the swabfor drawing the other parts thereof down the well-tubing.

A lever R for moving the bearing H is mounted on the side sill h, and alever B for moving the bearing H is mounted on the side sill i, thelevers having forked ends 13, connected by pivots z to the side sillsand. also connected loosely to the shaft 1 and. thereby to the bearings,so that either end of the shaft 1" may be moved slightly toward or awayfrom the-shaft n by its connected lever. A reach-rod T is connected tothe lever B, and a reach-rod T is connected to the lever R. Quadrants Sand S are attached to the side sills and extend against the levers R andR, suitable binding-screws 14 being provided for clamping the levers tothe quadrants when desired. Boll-crank levers U and U are mounted on therear parts of the side sills h and i, each by means of a pivot 15, andare connected, respectively, to the reach-rods. The handles of thelevers U and U extend rearwardly beyond the main frame, so that a manstanding at the rear ofthe vehicle may reach either handle conveniently.

A brake-head V is secured fixedly on the side sill h opposite to thepulley J, and a brake-head W is secured fixedly to the side sill iopposite to the pulley I.

A prop X is supported uprightly on the rear end of the main frame forsupporting the movable part of the derrick when. folded down forconvenience in moving the apparatus from place to place.

The construction above described affords the greatest facilities forrapid operations but in some cases slight modifications may be made sothat one lifting-cable only may be employed, in which case either thepumpbucket or the swab may be inserted in the well, as may be necessary.Usually water will be found in the well holding the gas down,

so that pumping will first be necessary. If the lever U be manipulated,the pulley J may be forced against the pulley F and put in motion, thelatter being driven by the belt 9, so

that the cable 8 would be partly wound on the drum K to lift thepump-bucket to the desired height, after which the pulley J would bewithdrawn from the pulley F to permit the bucket to descend of its ownweight, and thus the bucket would move up and down in the tubing of thewell until filled, after which the bucket should be drawn from the welland emptied. If the bucket should descend too rapidly, the pulley Jshould be drawn into engagement with the brake-head V to govern itsspeed. The swab may be operated in the well in a similar manner bymanipulation of the lever U, the pulley I being forced into engagementeither with the pulley E or the brake-head WV, as occasion may require.
